97/98 tube is year specific.
Same with 99-03.
They won't work with the 04+.
There is a solid 5~WHP gain from a 99+ airbox to the 97/98 guys...probably a smidge more so with a high flow filter in there, too.
Why would you make an air box where the tube goes out, then up, takes another turn and into the engine. Just stupid.
